At night time or 30 min after sunset
In Illinois they are also required when wipers are in use.
It depends upon driving condition (not time)
Full beam lights in foggy conditions will reflect the light directly back at the driver. Dipped headlights should be used instead.
If a drug has expired, it is in a condition and should not be used.
How far should headlights shine?
Concave mirrors are used in headlights.
No. Either use your regular headlights since they help other drivers see you. Also, slow down.
Headlights need to be used at night, when it is dark, and when windshield wipers need to be used.
Headlights are used during times in which it may be hard to see. In most states, headlights must be used when driving from dusk before sunset to sunrise.
300 feet
When it is raining during the day you should always keep your headlights on.
